Have you ever felt a fluttering feeling in random parts of your arm or leg? Some even get it in their eye .The sensations can also be described as a constant thump just under the skin. Yeah, well.....what is that?

A fasciculation (or “muscle twitch”) is a small, local, involuntary muscle contraction (twitching) visible under the skin arising from the spontaneous discharge of a bundle of skeletal muscle fibers. Fasciculations have a variety of causes, the majority of which are benign, but can also be due to disease of the motor neurons.

I get them. It’s a muscle spasm. It’s not really anything to worry about. I suggest the following:

1) Exercise regularly.
2) Get plenty of potassium and enough sodium (RDA for sodium is minimum recommended, not minimum). Bananas are a good source of potassium.
3) Stay away from muscle relaxers and alcohol.
4) Stay away from stimulants like energy drinks and espresso.
5) Tell your family that you love them (this won’t help the spasms, but it’s a good idea anyway).
